The real Beast roaming around the Super 15 rugby fields is Sharks captain Bismarck du Plessis.
The bloke next to him at loosehead prop, Tendai Mtawarira, is dubbed the Beast who provokes rumbling shows of affection from supporters when he heads off on a run.
His impact, though, is cosmetic compared with du Plessis.
That showed up at the weekend when Mtawarira sat injured in the stand and his teenage replacement, Thomas du Toit, helped engineer the set-piece demolition of the Highlanders. He was impressive and looks a strong prospect to make more of an impact than Mtawarira, who is a decade older.
The real fiend, though, is du Plessis, the senior hooker and captain of the Sharks who dispenses leadership, punishment and direction with relentless venom.
